phpdesk,
Thanks for the mod.
In the image below, a regular member is looking at the admin's profile page, "About Me" tab.
You can see that your block displays normally at the top, but the fields that were created are repeated below. Maybe defining the new user profile fields created by this hack as "editable, hidden" the actual owner of the profile can still view/edit it, but it does not show like that in the public profile except within your box.
Edit: This is same problem Mr. Running just reported above.
